DOOR-SECURER.

To all whom itmug concern:

Be it known that I, THOMAS C. Moore, a citizen of the United States, residing at the city and county of San Francisco and State. and useful Improvements in Door-Securers, of which the following is a specification.

This invention relates to a door lock and particularly to an inside detachable form of To lock which may be applied or removed wheneveg" desired.

i I n e of the objects of the present invention is to provide a simple, substantial, cheaply manufactured lock of the character. 'demay be adjusted to fit any standardjdoor and which may be quickly applied or removed. Another object of the invention is to provide a locking lever by which the stop on the lock may be forced t ghtly up against the door, thereby 81111111- urther objects will hereinafter appear.

he invention consists of the parts and the combination and arrangement of-parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a perspective view of the lock. Fig. 2 18 a perspective view of the sliding Fig. 3 is a perspective view of the locking lever.

Fig. 6 isa'sectional view of a door showing the application of the lock.

Referring to the drawings in detail, A indicates a main locking plate upon which is plateia Formed on one end of the main locking projeetion,-suc h as shown at 2. which is so shaped that it 'maybe inserted in an'ecess 3 formed in the striking plate 1 with which practically all door locks are equipped. Formed on the opposite end of the main locking plate and on each side thereof is a plurality of alined teeth 5, and adapted to interlock with said teeth to secure the sliding plate against movement when the lock is in use, is a pair of downwardly ex tending lug-like projections 6. For thefpn rpose of preventing separation of the sliding plate with plate, except such as may be secured by perspective view of the main .teeth while impart a pivotal or swinging the main locking plate iszin offsetrelation tothe main locking -tl1erein is specification of Letters Patent.

endwise sliding movement, a pair of guide lugs 7 are provided. These lugs, together with the lugs (5, are formed integral with the sliding plate. The lugs (i are positioned so that they may the lugs T are merely folded over the lower side of the main plate to prevent separation or removal of the sliding plate, except by endwise movement.

Formed on the forward end of the-sliding plate is a pair of upwardly,extending lugs 8 which are perforated, as at 9, for the reception'of a locking lever, such shown in Fig. 3. Thislever consists of a handle sec tion 10, a head member 11 and a pair of pintle -members 1.2 which are formed intogral with the headmcmber. The pintles 12 formed on the lever are adapted to be supported by the perforated lugs formed on the sliding plate and it is therefore possible to movement to the lockinglever as will hereinafter be described.-

Interposed between the sliding plate and plate is a stop plate/13.

be entered between the This plate is adapted to cooperate with thev sliding plate to secure the door 14 against being opened when the lock is applied. The stop plate 13 isso mounted that a limited sliding movement may be imparted thereto, this being accomplished by forming a longitudinally disposed slot 15 in its rear end 'into which projects a pin 16 secured on the sliding plate. The.

movement of the stop plate with relation to the sliding plate is thus limited and separation of the two plates is also prevented. To permit a free swinging movement of the locking lever 10 between the perforated lugs 8 a recess has been formed between the lugs, as shown at 17. This recess is formed by cutting out the metal between the lugs and thereby forms a space in which the head member of the lever may freely swing when the lock is to be ap plied; This is accomplished in the following manner:

The sliding plate. the stop plate 13 and the locking lever carried by the sliding plate are first moved rearwardly on the main locking plate. This is then applied to the door in such a manner that the offset section 2 will enter the recess 3 formed on the striking plate of the door. The doorpro wr is then closed and the latch 18 contained top of the offset portion, thus temporarily permitted to snap into place on securing it in place. The locking lever is nowswung to the dotted line position shown at 19 (see Fig. 6) and the sliding plate, to-

gether with the stop plate, is moved in unlson until the stop plate engages the inner surface of the door, The lugs'6 are next pressed downwardly into engagement with.

the teeth 5 and the lock is finally secured by depressing the lever 10. Depression of the lever causes the-forward end of the head member 11 to engage the stop plate andforce this tightly up against the door. Considerable pressure is exerted against the would prove door in this manner and the lock is forced firmly into position,

function of a cam when depressed. The lever is furthermore locked in this position,

as the pi votal'mounting of the same is such that it'assumes an inclined position beyond the center line drawn through'the'pivotal mounting, thus preventing the lever frpgpbecoming accidentallyreleased if the door should be violently shaken or handled.

The lock thus applied cannotbe removed" row of teeth 5 and the lugs 6 engaging the arts of which the lock is same, and, as all ormed of comparatively constructed are;

heavy metal, it can readily be seen that it will be almost impossible to force the door by external pressure.

be applied as any door,

A lock constructed as here shown should prove of great utility to every household, and should be particularly useful totraveling men and the like who are constantly occupying strange rooms in hotels, as the lock, as here shown, can be conveniently carried in the pocket or in a grip and may be quickly applied when retiring at night and inst as easily removed when not required. t may a safety or additional lock to as it does not interfer'e'with the o eration of any other lock that maybe emp gyed. v I

hile a more or lessspecific structure is here shown,-I wish it understood that the design and shape of the several parts employed may be varied and that the materials an finish of the several parts may be such as the lever serves the,

the door and the jamb as the experience and judgment of the manufacturer. may dictate. Y

Having thus described my invention, what I claim and desire to secure by Letters Pat- 'ent is:

1. A detachable door locking device including a main locking p'latehaving an annlar bend-at o'neendadapted to engage the lock mortise between the door edge andthe casing and having notches or serrations on opposite edges of the opposite end, a plate having downturned guiding clasps slidable on thelocliing plate, and with downturned lugs to engagethe notches of the main plate, a plate between the two having'a limited sliding movement, an upturned end adapted to abut against 'the door when'closed upon the locking plate, and a lever fulcrumed between lugs on the main slidable plate, said lever being mounted to swing in a plane plate so that its outer end will-abut against the uptlirned end of the intermediate plate to retain said plate in contact with-the door.

2. A detachable door locking device including a main locking plate having an angular bend at one end, adapted to engage the lock mortise between the door edge and the casing and having notches or serrations on opposite edges at the opposite end,.a-

vnormal to the surface of a main slidable main sliding plate having down-turned guiding clasps slidable. on the locking plate and with lo'wn-turned lugs to engage the notches o the locking plate, an intermediate'plate between the two and slidably mounted between the same, an up-turned end on said plate adapted to abut against intermediate plate to limit the movement thereof.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. v
